Product Description

The KUC711AE101 is a High-Performance Central Processing Unit (CPU) Module within the AC 800M controller family. It serves as the “brain” of the control system, responsible for executing user-defined application logic, processing input/output (I/O) data, managing communication tasks, handling real-time scheduling, and overseeing system functions. It operates within a dedicated AC 800M controller base unit (e.g., PM851, PM861, PM891).

Key Features

   • Fieldbus Support: Extensive support via communication interface modules (CIMs) for Profibus DP (Master/Slave), Modbus RTU/ASCII (Master/Slave), CANopen, etc.
   • OPC Integration: Supports OPC DA and OPC UA for connectivity to HMI/SCADA, historians, and third-party systems.
6. Rugged Industrial Design: Built for harsh environments with high immunity to electromagnetic interference (EMC), vibration, shock, and wide operating temperature ranges.
7. Programming Flexibility: Programmed using ABB’s Control Builder M Professional engineering tool, supporting all IEC 61131-3 standard languages: Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Sequential Function Chart (SFC), and Instruction List (IL).
8. Security Features: Includes user access control, password protection, and program security mechanisms.
